difficult to say, we don't know what you want to do? What I can see form the ( very compressed ) online version already, is , that it ( the town/ coastline I mean) is not sharp. You can't create details that are not there . So, I might improve the clouds a bit , make them more dramatic, to led the focus away from the unsharp details of the town .
But, as pasay said, you ask 100 people what to do, you will get 120 different opinions.
